Most recently, Chakan's incremental SNDi rose from 4.97 to 6.62 between 1991-2005 and 2006-2020. In terms of the aggregate network, Chakan ranked 154th out of 157 cities in Maharashtra and 1694th out of 1868 in India as of 2020.

For the full network, Chakan became more connected from 1975 through 1991-2005, then grew more sprawly from 1991-2005 onwards, while Pokhara became more connected from 1975 through 1976-1990, then grew more sprawly from 1976-1990 onwards and Songyuan became progressively more disconnected. Chakan and Pokhara have been converging in their street-network character since 1975.
